CHARLES A. BORT-IIN. OF OAKLAND, CALIFORNIA.

WATER-HEATER.

Application led September 25. 1911.

To a?? zrlzom 'z may concern Specification of Letters Patent.

Be it known that l. CHARLES A. Boutin'.

a citizen of the I nited States. and residing at Eleventh and Broadway. in the city of Oakland. county of `Xlameda. and r-tate of California. have invented certain new and useful Improvements in 'Water-Heaters: and I do hereby declare the following to be a full. clear. and exact description of the; said invention. such as will enable othersskilled in the art to which it most nearlyappertains to make. use, and practice the; I

spud 1s divided by the center wall 4, form- This invention relates to improvements in the former is threaded to receive the plpe 8. The passage 6 continues downward to near water heaters. and consists in the novel construction and arrangement of the parts.

The objects accomplished are the production of a heater with a large heating arca. whereby a. small quantity of water is acted i upon by a relatively large Quantity of h eat. and capable also of serving as a boiler pedestal.

f bastion.

Broadly the invention consists of a conical water jacket having a corrugated Inner surface. adapted to be acted upon by the' flame issuing from an annular Bumsen; Chamber 13 provided with bolts bv which burner attached to the base of the cone. The apex of the cone is truncated and provided with a vent, to carry off the products f of combustion. The apex of the water jacket terminates in athreaded spud adapted to be screwed into the bottom of a.

kitchen boiler or reservoir.

This spud is divided by a center wall. one passage;s providing an outlet from the top of the water jacket. the other forming an in-f ternally cored passage leading to near the bottom of the water jacket and is adapted to conduct the cold water from the bottom of the boiler to near the bottom of the water water from the top of the water jacket to near the top of the boiler. forming a thermosyphon internal circulation from 'the boiler through the heater and back into the boiler. A bridge across the apex of the cone inside l' I must pass between the inner circumference the heater, provides a socket for the recepcombined heater and boiler.

In detail the construction consists of the heating cone comprising the outer wall 1 the inner wall 2, closed at the bottom and terminating at the top in the spud 3. This ing two passages 5 and 6. The mouth of the bottom of the water jacket, being formed by the wall 9 cast integral with the outer wall, see Figs. 'z2 and 3. The cone of the water jacket is truncated which provides an escape vent 10, for the products of com- The bead 11 around the vent engages the flue 12 which is clamped thereover. and adapted to receive a vent pipe.

The Bunsen burner comprises the annular it. is bolted to the base of the heatihg cone, which is provided with the dependingl flange 14. The aspirator neck 15 is bolted to and communicates with the annular chamber 13, and is adapted to be connected with the gas service, and is provided with 'the air inlets 16 for the proper admxtnre of gas and air for combustion- The chamber 13 is provided with the outlet slots 1T= adapted to play the flame against the heating surface of the cone.

To increase the heating surface the inner wall 2 of the water jacket is augmented by ccrrugations. The over-hangingr convolutions being provided with depen ing spines 1S. around and among which the llame from the burner plays in its passage through the heating cone. To regulate the quantity of free air admitted to the heater. to support combustion. the circular damper pan 19 seton the pedestal 20 by the set collar 21 is provided. The air admitted to the cone, except that passing through the burner,

of the burner. and the outer circumference of the pan; the quantity being regulated by raising and lowering the pan in an obvious manner. This an also catches any condeusation dripping from the heating sur-1 face. retaining it until evaporated by the= heat. The opening '2:2 is rovided in this.- pan for the introduction o a pilot light or g taper for igniting the burner. For convenl ience in installing or removing the burner. it is divided as at. :23 to pass the pedestal '20.

The heat absorbed by the inner wall '2 is communicated to the small body of water, 1 confined between it and the outer wall l.

If it is desired to use the heater independent of the boiler, the inlet opening I3 at the top is formed to receive a pipe connection with the water service: the outlet 'T being piped in the desired manner. In combination with a kitchen boiler as illustrated; for domestic purposes the boiler is installed in g the usual manner, the inlet pipe 24 being connected to the water service and the outlet pipe :25 connected to the house service. The spud 3 is screwed into the central opening in the bottom of the boiler. the weight of the whole being supported by the pedestal 20. The gas service is connected to the burner, and the sediment cock 26 screwed into the opening provided for it in the lowest point of the water jacket, this provides a means for draining the s vstem when accumulations make it necessary.

The apparatus operates as follows: When the burner is lighted the heat is absorbed by the heating cone and transmitted to the water. The products of combustion passing out through the vent i e, which preferably leads outside the bui dlng. The water expanded by the heat rises from the heating cone and is forced u through the stand ipe 8, and discharge near the top of the iler, whence it paes through the outlet pipe 25 if a tap in the house service is opened. The hot water assing from the water 'acket is replaced y water flowing from t e bottom of the boiler, through the passage 6 to the bottom of the water jacket. If no water is drawn from the s vste'm, an internal circulation is set up. the whole body of water circulating 'through the heater, which progressively raises its temperature to the desired point. Should the heat from the gas flame be maintained the water with in the boiler will expand and be forced out through the cold inlet pi e 24. until the radiation is equal to the eat absorption; in this manner excessive pressure is provided against in the heating s vstemx Itis preferable to cast the heating cone integral as illustrated; however modern practice in the metal arts makes it possible to build it up otherwise. Applicant therefone does not wish to be limited to the exact :forms shown, and speciically described. Q
